Level

Each borg has a level associated with it. A borg's level starts at 1 and increases as it gains experience. The maximum level attainable through normal leveling is 10. Each time a borg levels up, its maximum HP increases; the size of the increase depends on the borg and is the same for each level-up. The maximum ammo capacity of some borgs also increases as they level up. Finally, there are a few Death Borgs who change in some way when they reach level 10. When Sigma II, Lambda II, Alpha II, and Zeta II reach level 10, they gain an extra Death Eye. The extra Death Eye allows these borgs to fire more shots at a time, making it worthwhile to level them up to level 10. Also, when Gamma and Gamma II reach level 10, their melee attacks shoot out short-range beams similar to those created by Sword Knight's melee attacks.

Level-up Schedules
A borg's level-up schedule determines the experience values at which they level up. There are three such schedules.

Normal
See the list of borgs following this schedule. The first level-up occurs at 10 experience, and each subsequent level-up requires 10 more experience than the last [lv x ((lv - 1) x 5)]:


 * Level 1: 0
 * Level 2: 10
 * Level 3: 30
 * Level 4: 60
 * Level 5: 100
 * Level 6: 150
 * Level 7: 210
 * Level 8: 280
 * Level 9: 360
 * Level 10: 450

Fast
See the list of borgs following this schedule. The experience values needed for each level-up are half those needed in the normal schedule [lv x ((lv - 1) x 2.5)]:


 * Level 1: 0
 * Level 2: 5
 * Level 3: 15
 * Level 4: 30
 * Level 5: 50
 * Level 6: 75
 * Level 7: 105
 * Level 8: 140
 * Level 9: 180
 * Level 10: 225

Slow
See the list of borgs following this schedule. The experience values needed for each level-up are twice those needed in the normal schedule [lv x ((lv - 1) x 10)]:


 * Level 1: 0
 * Level 2: 20
 * Level 3: 60
 * Level 4: 120
 * Level 5: 200
 * Level 6: 300
 * Level 7: 420
 * Level 8: 560
 * Level 9: 720
 * Level 10: 900
